Minus L-carnitine, fatty acids would have a difficult time permeating the walls of the mitochondria. Energy, stored in carbohydrates and fats, is required to work the muscle. Carbohydrates are converted from glucose to glycogen, to be stored in liver and muscle cells. Eventually, the body turns to fat storage for energy, and possibly, with more ease in the presence of L-carnitine. This is where L-carnitine as a supplement enters. During high energy output, the supply of L-carnitine becomes exhausted. Is it possible to compensate for this decrease solely through metabolic processes and diet? Or is an additional carnitine supplement needed for the extra boost? Judging from the variety of carnitine products now on the market, apparently many believe an additional outside source proves beneficial.

L-carnitine transfers long-chain fatty acids, such as triglycerides into mitochondria (a cell's energy powerhouse), where they may be oxidized to produce energy. L-carnitine is a very popular supplement that promotes growth and development. It is also used for fat-burning, increasing energy, and improving resistance to muscle fatigue. L-carnitine has also been shown to help build muscle and maintain cardiovascular health. It is also great in dieting, as it reduces feelings of hunger and weakness

Core Nutritionals - Acetyl-L-Carnitine Dietary Supplement

Acetyl-L-Carnitine (ALCAR) is a little bit like your 401K: you need it, you know you should pay attention to it, but it's not exactly the sexiest topic. We know; we feel you! But we also know that ALCAR is one of the most fascinating, useful, and physiologically exciting workout supplements on the planet. You're hard-pressed to find a single other ingredient that is involved in so many critical bodily processes: fatty acid and carbohydrate metabolism, neurotransmission, exercise performance and capacity, brain function - the list goes on! So, like your 401K contribution, don't forget to pay into your ALCAR fund. L-carnitine is a derivative of the amino acid lysine and, as certain conditions outpace the body's ability to produce it, l-carnitine is considered a conditionally essential amino acid. While endogenous biosynthesis of l-carnitine from the amino acids lysine and methionine is sufficient for essential processes - along with dietary sources of carnitine from protein-rich red meat, for example - dietary supplementation of carnitine may pose benefits in certain physiological conditions.

L-Carnitine

L-carnitine is a non-essential amino acid that helps to maintain overall good health by facilitating the transfer of fatty acid groups into the mitochondrial membrane for cellular energy production. Amino acids are generally used by the body for protein synthesis and as a neurotransmitter. Carnitine is primarily used to facilitate the transport of long-chain fatty acids into the mitochondria of cells for energy production. This process provides muscular energy by burning fat, and also prevents fatty build-up around vital organs.* *These statements have not been evaluated by the Food and Drug Administration.

What is L-Carnitine?
Carnitine helps make energy in your body. Most carnitine comes from the liver and kidneys, but you also get some from food. People take carnitine supplements for athletic performance, heart health, memory, and other issues. Most supplements contain one type of carnitine called L-carnitine. It's the same type that's in food. The other is D-carnitine which is the biologically inactive enantiomer to L-carnitine.
Why do people take L-Carnitine?
L-Carnitine is a popular supplement for athletes to increase performance. It also supports heart health for those with heart and heart related issues. And, it may help with thyroid issues, male infertility, thinking, memory, and side effects of chemotherapy.
Can you get carnitine naturally from foods?
Carnitine is in many animal products. Red meat has the highest levels. A 4-ounce beef steak has an estimated 56 mg to 162 mg of carnitine. Carnitine is also found in smaller amounts in chicken, milk and dairy products, fish, beans, and avocado.
